Only Ocular Response Analyzer® G3 measures Corneal Hysteresis and Corneal Compensated IOP (IOPcc) using patented technology to assess the unique corneal biomechanical properties of your patient. Corneal Hysteresis has shown to be an independent risk factor and more predictive of glaucoma development and progression than CCT or IOP1-3. Using biomechanics, IOPcc is less influenced by corneal properties than Goldmann applanation tonometry4.

Only Tono-Pen AVIA® continues to advance handheld tonometry with the all-new Quick-TapTM measurement mode. The same ready-to-use, calibration-free, and accurate operation, now with more confidence in fewer measurements. Trusted by clinicians for over 30 years. We share your passion for improving glaucoma care.
